She reported pain in her knees and ankles for a year and an oral ulcer 3 months ago, which had healed. Laboratory evaluation was remarkable for a low white blood cell count at 2.4 × 1000/uL (normal 5.0–13.0 × 100/uL), hemoglobin of 10.8 g/dL (normal 11.8–16.0 g/dL), and platelet count of 109 × 1000/uL (normal 142–424 × 1000/uL). Erythrocyte sedimentation rate was elevated at 45 mm/hr (normal 0–15 mm/hr). Antinuclear antibody was positive at 1:640 with a strongly positive antidouble stranded DNA antibody confirming a diagnosis of systemic lupus erythematosus (SLE). Urinalysis did not show proteinuria to suggest renal involvement. She was treated with prednisone and hydroxychloroquine resulting in improvement in her problems.
